Mercury expands when it is heated. This process is called thermal expansion.
Answer:
Hey buddy, here is your answer. Hope it helps you.
Explanation:
The force stopping the object's motion might be an obvious one - the ground! Friction is a force that slows or stops motion. Friction is the resistance to motion created by two objects rubbing against each other (the sled and the snow, for instance). Even air causes friction.
Answer:
<h3>The answer is 0.34 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
![density = \frac{mass}{volume} \\](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7Bmass%7D%7Bvolume%7D%20%20%5C%5C%20)
From the question we have
![density = \frac{4.05}{12} \\ = 0.3375](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7B4.05%7D%7B12%7D%20%20%5C%5C%20%20%3D%200.3375)
We have the final answer as
<h3>0.34 g/mL</h3>

The enthalpy of reaction or ∆H reaction is the difference between the bond energy of the reactants and the bond energy of the products.
<h3>What is ∆H reaction?</h3>
The term ∆H reaction refers to the heat that is evolved or absorbed in a chemical reaction. It is also known as the enthalpy of reaction.
The question is incoherent but I will try to answer as much as possible. Using the values of bond energy, ∆H reaction = Bond energy of reactants - bond energy of products. This will give us the enthalpy of reaction.
